Chemical Properties
Lead chromate is an orange or orange-yellow
crystalline solid or powder.
Uses
It is used in chemical analysis of organic substances. pigment for paints and inks; in oil and water colors; printing fabrics, decorating china and porcelain; in chemical analysis of organic substances; in traffic paints.
Uses
Lead chromate (PbCrO4) is found in nature as yellow crystals in the mineral crocoite. It
can be produced by reacting lead chloride and sodium dichromate. It is a popular and safe
yellow pigment.
Uses
Lead chromate, “chrome yellow” PbCrO4, yellow precipitate, by reaction of soluble lead salt solution and sodium dichromate or chromate solution.Used as a pigment; basic lead chromate, red solid, insoluble, formed by heating lead chromate and sodium hydroxide solution.
Definition
ChEBI: A chromium coordination entity comprising chromate and lead(2+) ions in a 1:1 ratio
Health Hazard
Lead chromate is a suspected
human lung carcinogen and can cause chronic
lead poisoning.
storage
Color Code- Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. I ead chromate must be stored to avoid contactwith oxidizers (such as perchlorates, peroxides, permanga-nates,chlorates, and nitrates) andchemically active metals(such as potassium, sodium, magnesium, zinc and ferricferrocyanide), since violent reactions occur. A regulated,marked area should be established where this chemical is handled,used, or stored in compliance with OSHAStandard 1910. 1045.
